OP.
I wasn`t going to let this one go ...
I`ve looked at all my WD`s on ABS , BCM , SRS etc but don`t have one for your year . They all do follow a theme though in that there are two power feeds from the engine bay fusebox and one from the cabin fusebox . The power supply through the BCM is relative to the ignition switch position , the two engine bay when key at position 1 , 2 and 3 ; the cabin with key at position 2 .
The main point though is that all pass through connector 54/3LB . This is sited above the CEM and is the main one that passes through the bulkhead (under the skuttle panel) .
As a 2005 , i assume a facelift model these are well known for water ingress problems in this area . There are countless posts on this problem .
I would suggest that you check these connectors for corrosion . Whilst there you could test the wiring continuity .

I`ve included a 2004 model diag. which may not be the same as yours but gives an idea on what i`m rattling on about .
Key areas are , 7/164 (accelerometer) 54/3LB (connector) , 11C/9 11B/14 11B/19 (fuses)
